Built on the CoroDrill 870 platform, this insert-style drill uses a solid carbide tip with a PM insert geometry and a TiAlN coating applied via PVD process. The 142-degree included angle geometry promotes self-centering and reduces thrust force at entry. With a 0.75-inch cutting diameter and a package quantity of one, this drill tip is suited for high-production environments where tool changes must be fast and consistent. Licensed machinists and tooling specialists are the primary users of this component.\u003c\/p\u003e\n\u003cp\u003eThis replaceable tip is intended for use in CoroDrill 870 series drill bodies with an insert seat size of 19. It is well suited for ferrous and difficult-to-machine materials in both production machining centers and manual mill setups. The TiAlN coating provides oxidation resistance and extended wear life at elevated cutting temperatures, making it appropriate for dry or minimal-quantity lubrication (MQL) cutting strategies. The part is sold individually but carries a minimum order quantity of two units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide tip construction in manufacturer grade 4334 for wear resistance\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating via PVD process for heat and oxidation resistance at high cutting speeds\u003c\/li\u003e\n  \u003cli\u003e142-degree included angle for stable entry and reduced walking\u003c\/li\u003e\n  \u003cli\u003ePM insert geometry for controlled chip formation\u003c\/li\u003e\n  \u003cli\u003eCoroDrill 870 platform with insert seat size 19 for repeatable tip indexing\u003c\/li\u003e\n  \u003cli\u003e0.75-inch cutting diameter compatible with standard drill body holders in the 870 series\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with CoroDrill 870 series drill bodies requiring an insert seat size of 19 and a 0.75-inch cutting diameter tip.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or tooling technicians. Ensure the drill body is fully secured in the spindle and the machine is powered down before indexing or replacing the tip insert. Use the manufacturer-specified torx or clamping key for proper tip seating — do not overtighten by hand or with improvised tools. Verify insert seat cleanliness before installation to ensure full contact and accurate runout.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 142 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 4334\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Geometry\u003c\/strong\u003e: PM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: 19\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CoroDrill 870\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 18.5 x 15.75 x 5.51 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.053 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SANDVIK COROMANT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7357939\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51729283514674,"sku":"7357939","price":449.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a1c60e42b88dae248ccf037a21b2e074_57275f51-9c26-46e4-9fe6-4d01978c3150.jpg?v=1788702438","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7357939-replaceable-tip-drill-0-75-in","provider":"Voomi Supply","version":"1.0","type":"link"}
